Last Febraury to March, I had some stomach issues which a lot of GPs said was either acid or gastritis. Symptoms were belching, gnawing sensations in the stomach after a few hours of eating, no genuine hunger, etc. I was put on a month of omeprazole but it took me about 6 weeks to feel better.

Starting late March, symptoms were slowly fading away. April was generally okay -- issues were 99% gone. Last May 1, I left the country to have a vacation all over Europe. Strange enough, I enjoyed it and I feel like I did not experience my stomach issues. It was so awesome.

Now I just returned to my country and had my first dinner here since I left. For some reason, I felt stressed because of all the work I left behind, all the pests I had to kill in the house, and other petty frustrations upon returning from a wonderful vacation. And after 3 hours of eating, I started feeling these ticklish sensations in my tummy that kinda feels like hunger.

The symptoms aren't as bad as before but I feel that this could be the beginning again of my stomach issues

Is this too mich of a coincidence to be stressed and feel stomach issues again?

The stomach and digestive system are the first parts of the body to be effected by stress and anxiety. That is why so many of us here suffer from stomach issues (myself included). I would imagine that the stress of coming back from vacation has you very tense and it makes perfect sense that it is effecting your stomach. Try not to get lost in the fears of the stomach problem returning full force. If you are still on meds, keep taking them. If not, then maybe consider taking the omeprazole again for awhile while you work through this initial stress of being home. Everything will be alright and at least you have the experience to know how to deal with it now. Good luck
